How to Make the Recipe

Step 1: Brown the Ground Beef

In a large skillet over medium heat, cook the ground beef until it’s browned, breaking it up into small crumbles as it cooks. Drain any excess fat.

Step 2: Sauté the Vegetables

Add the minced garlic, chopped onion, and chopped green peppers to the skillet with the ground beef. Cook for 3-4 minutes, or until the vegetables have softened.

Step 3: Add the Tomatoes and Broth

Stir in the diced tomatoes, tomato sauce, beef broth, Worcestershire sauce, salt, and pepper. Bring the mixture to a simmer.

Step 4: Stir in the Rice

Add the uncooked rice to the skillet, stirring to combine. Cover the skillet and simmer for about 15-20 minutes, or until the rice has absorbed most of the liquid and is tender.

Step 5: Assemble the Casserole

Transfer the beef and rice mixture into a greased casserole dish. Sprinkle the shredded mozzarella cheese evenly over the top.

Step 6: Bake

Preheat the oven to 350°F (175°C) and bake the casserole uncovered for about 10-15 minutes, or until the cheese is melted and bubbly.

Step 7: Serve

Once the casserole is ready, let it cool for a few minutes before serving. Enjoy hot, and feel free to garnish with fresh herbs like parsley or basil.

Tips for Making the Recipe

Use Day-Old Rice: If you have leftover rice, it works great for this dish. If using freshly cooked rice, make sure to let it cool down a bit before adding it to the casserole.
Don’t Skip the Worcestershire Sauce: It adds a deep, savory umami flavor that really elevates the dish.
Adjust the Seasonings: Taste the beef and rice mixture before transferring it to the casserole dish. Add more salt, pepper, or Worcestershire sauce if needed.
Add More Cheese: For a cheesier dish, feel free to add more mozzarella or even a different cheese like cheddar or Parmesan.

How to Serve

Serve this casserole as a standalone dish or pair it with a side salad, garlic bread, or roasted vegetables. It also works well with a dollop of sour cream or a sprinkle of fresh herbs like parsley or basil for added freshness.
